Application inea April 1,6, V1925.` seriailivo.A 23,721.

My invention relates to a machine for placing rims uponv pneumatic tire casings prior to the vulcanizat-ion thereof, andy it hasV particular relation to a novel device adapted to be used in connection therewith. Y One object of my invention consists in providing a device which will increase the speed of production with reference to presses and yreduce the amount of labor incident to the operationthereof. i

Another object of my invention'is to provide an attachment for a rimming press, yadapted to be used for applying rims to pneumatic tire casings, which will permit one tire casing to be supported and prepared for theapplication of rims while the rimming press is being operated to secure rims on a second tire casing.

In the manufacture ofvpneumatic tire casings, 'after the tire has been built and prelparatory to vulcanizing it, an air bag, 'or

other core, is placed within the casing. L

pair of metallic rims are then" placed one on each side of the beads of the tire, the rims are drawn towards each otherV so as to bring the beads of the casing together, and

the rims are clamped in that position by means of bolts. The casing, with its assembled core and rim, is then ready to be placed in amoldfor curing.

In order to draw therims into the' desired position, a press, usually known as a rimming press, is employed. As heretofore constructed, the press consisted of a machine having a stationary top, or work supporting table, provided with a large circular opening` therein, and a plurality of power actuated arms for drawing the rims together. It was operated by placing a lower rim on the table surrounding the opening, the casing,vwith its core already inserted, was placed thereon, and a second rim was placed on the upper bead of the casing. rlhe machine was then actuated to cause a plurality of arms tovrise through the circular opening, engage the upper rim, and draw it downwardly while the operator placed bolts through suit-ably provided 'openings inthe rims tol hold them in the clamped relationship. The casing, with its attached rim was then lifted from the machine and a lower `rim for a second tire casing placed thereon.

this type of press it was ,possible to 'prepare only one casing at a time and the operator was required to wait until the process of applying rims to one casing was completed andthe casing removed `from the press before additional rims could be ap-V plied to a second casing preparatory to Vclamping them together.V 'With this method of operation, only a single operator could c work efficiently and the clamping mechanism was in actual use only a small portion 'of the time. i 'i My invention .obviates the delay heretofore encountered in this manner by'providing a device adapted to be attached to the rimming presswhich is so constructed and mounted that the rims of one casing may be i positioned'thereon while rims are being applied to another casingby the press. ln a machine constructed in accordance with my invention, after thel first casing, with its assembled rims, isremoved, a second. previously positioned casing( and rims maybe manually swung into position4 over the press and the rims clamped without removing them from the-device. I

For a more detailed descriptionrof my invention reference may now be had to the accompanying drawings, forming a part of this specification, in which;

Fig.` l is a yperspective view of a ri1n-.

mingpress with my novelattachment apn plied thereto; f

Fig. 2 is a fragmentary elevational view of the attachment, portionsthereof being shown in cross section for the sake of clearnessy'and v Fig. 3 is a plan view of the attachment illustrated'in Fig. 1. l j c i' Inkpractising .my invention, I have incon' porated the novel features thereof in an attachment adapted to be associated with a y rimming press 10 mounted' upon a ,suitable vfoundation and provided, for its operation,

with a suitable source of power supply (not shown). The rimming press, in connection with which my invention is illustrated, is of the type disclosed and fully described in a co-pending application of Robert W'. Sny-v der, Serial No. 43,047, filed July 11, 1925.

This pressA comprises a ciriculargframe member 18,'having horizontal circular top .40 In order to maintain the table 22 at the member 14, which is provided with a circular opening therein. A plurality of arms 16 having angular or hooked end portions 17 are normally disposed below the surface of thetop'member 14. The arms 16 are'pivotally mounted on supporting lugs 18 on the member 13 by vmeans-of pins 19, and are Y Vadapted to be moved upwardly through the opening 15 for the purpose of engaging the metal rims which are applied to the bead1^-` Vportions of tire Vcasings', ,as shownrin ydot and dash lines in Fig. 2. 'A weight member 2O is attachedto one endv of each ofthe arms 16 to actuate the hooked ends 17 thereof upvwardly to hook over the upper rim member.

VAn attachment '21,v comprising the essentialsV of my invention is illustrated in the form of an oblong table 22 which is rotatably mounted upon a centrally 'disposed vertical shaft 23, journalled,I at its upper end, in av bearmg 24, which is mounted upon the frame vmeinber27 isY secured to the table 22 at its central point bymeans ofrivets or bolts 28,

rand is adapted to receive the upper end of the shaft 23. In order to prevent rotation f of the shaft. 23 with respect to the collar member 27, a key'member29, as best shown in Fig. 3, is inserted within the collar.V

However, this construction isnot absolutely essential to assure efficient operation of the device as the shaft 23 maybe formed with a Vsquared end .toiitvin a'squared socket inV the table 22 or it may be rigidly supported nut for the lower one.

l and its upper end jour'nalledin ythe collar member 27.

proper height with respect vto the top member 14, and to compensate for wear in the bearings, two collar members'30, in threaded engagement with the shaft 33, and resting on the. bearing member 25, are provided. The uppercollar member serves as a lock If it is desired to readjust the height of the table top, thev upper collar is moved away from the lower one so as to release it, the lower one is turned unt-i1` the desired'height is reached, and the upper collar screwedl into enffagement therewith. Ifl desired, roller or bali vbearings may be employed between the lower collar member 30 and the top of the bearing niember 25. f

The table 22 is'provided, adjacent each end, with a relatively large'circular opening 32. Surrounding the opening 32, and concentric therewith in the table 22 is a groove 33 within which aV circular ring 34 fits snugly,`as best shown in Fig. 2. This ring A is Vsecured to the table by means of suitable Y I Y screwsV 35. It is evident that the table 4rims over the top of the rimming press. V'their normal posltlon, the arms ofthe may be machined or cast with this rino;y

"recess 38 on the upper side andV with .acircumferential ribl 39 on the Vlower side,

is adapted to lie upon the surface of the table v 22 in such position that the outer circumferential edge thereof willabut the Linner circumferential edge of the -ring- 34 and the rib 39 will vfit snugly into the 'circular opening 32 ofthe table 22. Likewiserother rings of various sizes may be held in place against the outer side of the ring 34 and in the groove 35 therein to support various sizes of rims utilized in applying rims to casings of different dimensions and types. The two rim members 40, which arey annular in form', aresimilar and are provided with inwardly extending annular flanges 41,V` which are adapted to engage eachother, and inwardly extending` offset flanges 42 which `engage beads 43 of a pneumatic tire casing 44.` rlhe flanges 41 are each provided with elongated openings 45, adapted to register wth each other and to receive T-head bolts 46, which areinserted by hand, when the rim flangeslll are in engagement with eachother, and given a half turn to lock the rims together. 1 f 1 In the operation of my device, a lower rim member 40 is placed so as to surround the opening 32, at one end of the table 22 while the other end thereof is inV engagement with the top member 14 of the press.` The rim is positioned upon the ring 37 so that the flange 42 fits snugly within the recess 33, as indicated in Fig. 2, and the tire casing 44, with a pneumatic core 47 disposed therein, is then placed over the rim. with the'beads 43 engaging the flange v42 of theV rim. The upper rim member 40 is then placed over the top of the casing and the rims are then ready to be clamped together. v f

The operator of the machine then manually swings the table about its, central pivotal point so as to bring the'casing and In re'ss are disposed below the level of the table 22, thus permitting the table to be swung so that it contacts lightly withthe top of the press. The Vpress is then operated Vin theY usual manner by applying suitable power and thev arms 16 rise through the open center of the rims and 'tire casing, the hooked ends 1'? .thereof engaging the yupper rim member 40, andY drawing it downwardly against the lower rim as shown in Fig. 2, thereby lirmlysecuring together the beads of the tire casing. In this position of the rims the T-bolts 46 are inserted through the Openings i td'ioek therifns and. tire beads iii close Contact. The hooked' arms 16 are then released andpermitted to fall below the top' surface of the press.' Vhi'le thev rims are being broughttogether by the arms 16 and the bol-ts 46 inserted 4through the flanges ofthe rims, another casing may be prepared l upon the other end of the table. 'As soon as the rims are secured together, the table 22 is again rotated so that the new casingV and rim may be swung over the press in the same manner as theiiist, and the assembled casing may be removed preparatory to assembling a third casing.

From this description of my invention, it will be apparent that two operators may work efliciently at a single kpress without interfering with each other. In the preferred method of operation, while one workman is operating the pressing elements and in the art that it is not so limited but that.`

various minor modifications and changes may be made therein without departing from the spirit of my invention or from the scope of thel appendedclaims.
